well of course you can port and polish. get the valve-package from delta cams
pistons:     flat top and 10:1 (or close) compression retained.  rods & bearings:   yeah - that's not breaking...

valves and valve springs are hard to find which means it might be custom.

im thinking about buying the lower internals for build up too. i did find 8.5:1 and 8.3:1 87mm pistons that would fit, im having problems finding rods though.
